When the men arrive at their new temporary homes, they notice that they only have one bed, meaning they will have to sleep with their 'experimental partner' much to the displease of their female partners.

We see the new couples getting steamy as Kaitlyn asks her new partner Michael: 'Do you sleep naked?' before showing Michael getting a massage from the blonde beauty.

Throughout the experiment, the couples will be guided by relationship experts and psychologists who said: 'It's like we will be holding up a mirror so that you can see how you behave.'

When Kaitlyn was asked by the psychologists about her concerns on the experiment, she says: 'I think Mike might fall in love with someone else'.

Tracy's experimental partner Sarge goes on to say: 'I find Tracy's confidence really sexy', to which she replies: 'I definitely can see that the grass could be greener'.

We see Felicity meet up with her partner Michael's experimental partner Kaitlyn, to whom she says: 'It is over. To a point where you can actually give this back to Michael' as she gives Kaitlyn her diamond engagement ring.
